How to Teach Your Baby to Crawl

The Stages of Crawling

Amelia Hunt started crawling at 7 months, but not in the traditional way. She had her own style: "Sitting up, she would slide across the floor on her bottom," says her mother, Gayle, of Hoboken, New Jersey. Amelia soon abandoned this for a new—albeit less efficient—method. She'd lie flat on her belly and move backward by pushing off with her hands.

Like Amelia, most babies will try a variety of crawling styles, from the butt scoot and backward inchworm to the bear walk (with arms and legs straight and bottom in the air, they "walk" on hands and feet) to the leapfrog (on all fours, pushing off with their legs and jumping forward). Eventually, though, most kids settle on the standard crawl. "By 9 months, Amelia was getting around on her hands and knees like a pro," says Hunt.

Learning Coordination

"Before crawling, a baby must first lose his infant reflexes—such as flailing his limbs when he's startled—and learn how to coordinate his arms and legs, which is no small feat," says Parents adviser Steven Shelov, M.D., chairman and vice president of Maimonides Infants and Children's Hospital of Brooklyn.

In addition, your little one can't bust a move until they win an important battle with gravity. "You've got to remember that when a baby is born, he suddenly experiences a pull of gravity ten times stronger than that in the womb," explains Jody Jensen, Ph.D., associate professor in kinesiology and health education at the University of Texas at Austin. "Being able to crawl means your child has learned to resist this pull of gravity while developing the strength to lift up from the ground."

Crawling Backward Is Still a Step Forward

Your little one may move backward at first. But with time, they will discover that by shifting their weight from one side to the other, they can coordinate their arms and legs and propel themself forward. (You'll probably notice that your baby spends the weeks—or months—before they actually crawl rocking back and forth on their hands and knees.)

Although most babies start creeping between 7 and 10 months, it's not unusual for a child to make their first move much later than this. Experts believe chubbier babies crawl later since it's harder to push up onto all fours and drag their extra body weight. And younger siblings may lack the motivation to move if an older sister or brother is constantly carrying them around or bringing toys within their reach.

Build Those Muscles

In order to crawl, your baby must be able to hold themselves up and maintain their balance using the muscles in their stomach, neck, arms, back, and shoulders. Starting supervised tummy time during their first weeks of life makes a difference.

Put them on a blanket or a playmat on the floor for three to five minutes two or three times a day. Place a toy just out of their grasp, or try to get them to reach for you. Whenever they lift their head, look to the side, or kick, they're developing strength in their upper body, core, and legs. As their muscles grow, steadily increase tummy time to a total of 40 to 60 minutes each day.

Be Sure to Babyproof

Your baby's newfound mobility isn't just exciting, it also changes their perspective on the world and their place in it. "Once your baby starts to move, he realizes that he can go after things that rolled under a couch or chase his mommy," says Jayne Singer, Ph.D., clinical director of Parent-Infant Mental Health at Children's Hospital Boston. "It's truly exciting and empowering for a baby."

It can also be bittersweet for you. While it's fun to watch your baby crawl, it's also the first sign that they don't need you quite as much. Their newfound mobility also means they're more likely to get injured.

"People underestimate a baby's speed and strength," says Steve Weinstein, president of the International Association for Child Safety. "Keep in mind that most accidents happen when parents are just six feet away from their child." If you haven't already babyproofed your house, do it now. Put baby gates at the top and bottom of staircases, and move houseplants—which can be a choking hazard—off the floor.

Start to Teach Discipline

This is also a good time to introduce the first stages of discipline. Now that your little one has started exploring, it's your responsibility to firmly but gently tell them no when they get too close to an electrical outlet or won't stop harassing the dog.

Of course, don't let anxiety about their safety get the best of you. "Smile and cheer him on as he moves across the floor," says Dr. Singer. "Your enthusiasm will encourage him to keep trying new things."

Voice Any Concerns

Talk to your child's pediatrician if your baby has not shown signs of mobility (such as scooting) by their first birthday, or if they crawl with asymmetric movements (like dragging their right leg). Otherwise, their style of crawling, or lack thereof, is likely fine.

They may not be interested in crawling because they're focused on building other skills, such as babbling. Be patient; your baby will find a way to get around when they're ready.

When Your Baby Skips Crawling

You've been waiting and waiting for your little one to start creeping across the floor, yet they seem perfectly happy to stay put. What's the deal? In about 5 to 7 percent of kids, crawling never happens. Instead, they go straight from sitting, to pulling up, to standing, and then walking. "Parents need to know that this is perfectly normal. It doesn't mean that your child isn't developmentally on target," says Jody Jensen, Ph.D., associate professor in kinesiology and health education at the University of Texas at Austin.

Most likely, your baby's temperament is playing a role. For example, placid babies are often content to stay in one place. Or your little one could be so focused on trying to communicate and say their first words that they're less inclined to test themself physically.

However, talk to your doctor if your 1-year-old isn't mobile at all and was also delayed with other physical milestones such as lifting their head and sitting upright. They'll want to rule out problems like low muscle tone and visual impairment—since babies who can't see objects at a distance don't have the motivation to go after them.

See How They Scoot

Here's a quick snapshot of four of the most common crawling techniques:

Standard: The classic crawl, in which they alternate a hand on one side and a knee on the other to get around.

Crab: By bending one knee and extending the other leg, they slowly propel themself sideways.

Commando: Often called the "army crawl," while lying flat on their belly, they manage to drag themself forward using their forearms.

Roll: Before they are strong enough to get up on all fours, some babies roll to get where they want to go.
